In general, if Brunswick "pours" your ball, you will use the same supplier as they do, Bayer, and you MAY use the same resin as they use in one of their coverstocks. Then again, you may not.
If you use Columbia300 to manufacture your balls (The G-Force series and the Uranium HRG were manufactured for Lane#1 by Columbia300.) then you will use Columbia's resin supplier, BASF. You may or may not choose to use the same exact resin forumla as Columbia did in one of their balls OR yo umay choose some other resin formula. It depends on what you want the ball to do and what core you have chosen.
Even Track and Columbia did NOT use the exact same BASF resin formula for every ball they made. They definitely used different cores and both were owned by the same company.
